These VB-TB4 valves are individual valves with floats to fit the 49-59mm Float size. The Solar Biz has many float sizes available to meet any installation need. The majority of the American battery market will use only a few standard sizes.

Batteries with no raised neck on the cover will typically use a 34mm float. Batteries with raised vent neck covers will typically use a 39 mm float. HuP Solar One Batteries use a 49mm and the Surrette 5000 series typically use a 59 mm float.

However, we recommend that a float measurement is taken using the float gauge BFS-005900 to ensure the proper float is selected. The float guide has a movable depth stop to measure your battery cell.

I agree that the prices are competitive. However, that’s of little comfort if they don’t process your order. After acknowledging my order on 9/2, over a week passed with no communication. I emailed customer service asking for status. They said they would check into it. A day or so later I was informed the order hadn’t shipped but would soon. Another two days passed and I was given a tracking number. I had requested they expedite the shipping because of the time they sat on my order. Nothing, no response. If the order arrives on the scheduled date it will have been nearly 2 weeks from the time they acknowledged the order. How on earth do these folks rate 5 stars? I should have used Amazon Prime and would have had my product more than a week ago.

TERRIBLE VENDOR! I paid $1360 for 4 Trojan SPRE 06 415 batteries. Would have been good price, BUT THEY SHIPPED 16 MONTH OLD BATTERIES, CONFIRMED BY ENGINEER FROM TROJAN! I sent photos of date stamps, but SolarBiz made no adjustments, did not offer to replace batteries. No way to know how long these "premium" batteries will last. DON'T DEAL WITH THESE FRAUDS! YOU WILL BE SORRY IF YOU DO!
i HAVE WAITED 2 MONTHS FOR THEM TO REPLY!
